A Department for Business spokseman said any further increases, even if they included a ‘ceiling’ limit, were unrealistic in the current climate.

“The proposals include a requirement for full pay [to increase] during maternity leave, albeit subject to a ceiling. There is a lack of clarity in this proposal which could expose the UK and other member states to serious additional costs,” he said.

The department also claimed that the UK’s maternity pay was already both “generous” and “progressive”.

But equality experts have claimed that improved payments could help women to feel valued by their employers and not forgotten when on leave. This, in turn, could persuade new mothers to return to work, saving UK employers re-recruitment and training costs.

Andrea Ward, employment associate at the law firm Hogan & Hartson, explained: “Although there will be increased costs for businesses, an uplift on maternity pay to support women during such an important time may well encourage them back to work and save employers money in the long run.”
